Re: [OpenIndiana-discuss] Access to ZFS viz CIFS from windows regularly hangs.
I have an update on my running CIFS and windows saga. Getting samba installed and joined to the domain is a challenge and a half, and is still not authenticating (trying on a test server). What I have done is stop using a dns alias to connect to the OpenIndiana server. So whereas before I was using the servers real name to connect to a H: drive (for my documents etc) and a dns alias (CNAME) to connect the company wide file share S: Drive. (the intention I could fail over to a different and just update dns). I had noticed that it was mainly the S: drive not responding while the H: Drive would continue to work (but not always). I changed my login scripts to use the OpenIndiana servers real name for the S drive as well, and have had not reported problems since. I did this change just over a week ago. Should OpenIndiana support a dns alias like this? It requires a registry change on a windows server to work, but I believe the registry change just effect that windows server, and is required for it to work at all.

Re: [OpenIndiana-discuss] Access to ZFS viz CIFS from windows regularly hangs.
On my home network I observed that when I turned a Windows XP host off a Windows 7 host declared that it lost access to the Samba service hosted from a Solaris 10 system. It was then able to reconnect to the Samba service on that Solaris 10 system even though the Windows XP host remained turned off. It is a problem that Windows uses random hosts on the network as directory servers and then blames the problem on the host which is actually serving up the data (as if that host was lost) if that random directory server goes away. This behavior seems like it would make dignosing issues more difficult. If you are using samba then there is configuration you can add to stop your problem in the smb.conf file, you can increase the os level to 99 just to make sure. [global] domain master = yes local master = yes preferred master = yes os level = 65 The inbuilt kernel CIFS server only does file sharing and therefore cannot be a master browser hence your windows 7 machine will be it.

Re: [OpenIndiana-discuss] Access to ZFS viz CIFS from windows regularly hangs.
The first thing to verify is your network and network interface. Run continuous traffic and see if there are any hickups. You can use /usr/sbin/ping for testing with larger packets. Also check the log files under /var/adm and /var/log. Also check output of 'fmadm -ev' and 'fmadm faulty'. Nothing shows in dmesg, or in the logs under /var/adm and /var/log no hardware errors are logged by zfs either. 'fmadm -ev' errors on invalid options and 'fmadm faulty' is clear (nothing to report). The nfs share to the vmware server seems fine as well, but it may be more accommodating of problems. Large file transfers initiated from a windows desktop run at 40 to 50 MB/s (desktop probably the bottle neck).

Re: [OpenIndiana-discuss] Access to ZFS viz CIFS from windows regularly hangs.
I had similar issues before I enabled TLER, and disabled the head parking on my WD Green drives. A quick Google shows some evidence of similar features on the 3TB Hitachis. I chose Hitachi because I didn't think they had this feature. I would have thought ZFS would have reported errors and removed them from the array if it was happening? I will go and search the internet. John ___ The contents of this e-mail and any attachment(s) are strictly confidential and are solely for the person(s) at the e-mail address(es) above.

Re: [OpenIndiana-discuss] Access to ZFS viz CIFS from windows regularly hangs.
Have you done a snoop (or wireshark) capture to see what the box is
doing during the pause?
It's possible that it's trying to talk to an AD server...

Another symptom is windows explorer hangs and the user has to wait for it

Just waiting a while ( a few minutes) and the box comes back.
I currently think the root cause is in openindiana somewhere but am at a
bit of a loss. I have tried many things and have still not fixed it. I think
the box is lightly loaded for the hardware spec but kernel load increases to
40% when a zfssnap is taking place.
Hardware spec.
2 x Xeon E6520 cpus
48 GB RAM
Intel HC5520 motherboard
3 x LSI SAS 9211-8i cards
Currently on openindiana 148
The box is joined to a windows 2003 domain.
Zpool tank is 3 way mirror of 7 x 3TB hitachi disk (using 21 disks in total,
zpool size of 19 TB, ) with 2 x SSD 8GB ZIL on each and 140GB L2ARC on
each, default checksum, no dedup and no compression.
Server operates as a windows home directory for 58 users (some laptops users
so just a backup location), a main shared drive for the company of 120
users.
It is also a nfs server to a vmware vsphere 4 server hosting 10 virtual
machines.
There are only 8 active production file systems, and 12 backup file systems
from other hosts (done out of hours).
Zpool iostat peaks at about 35 MB for the pool mostly around the 0 to 7 MB
level.
Turning of time-sliderd does not stop the problem. (backups run out of
hours)
A dtrace -n 'sched:::off-cpu { @[execname]=count()}'
Used to give a sched count in the 6 to 7 fiqures over 3 seconds, but turing
apci off with
#eeprom acpi-user-options=0x8
Reduced this to 5 figures.
What can I do to identify the problem to be able to fix it?
Thanks
